Question

Django’s ORM supports querying from a specific database (when multiple are defined in your project) via the .using() function for filter-based operations.

e.g. MyModel.objects.filter(name='Bob').using('my_non_default_database')

How would you do the equivalent when creating new records, via the class MyModel() or shortcut like get_or_create()?

Answer 1

using is a method on the MyModel.objects manager, so you can do

MyModel.objects.using('my_non_default_database').get_or_create(name="Bob")

If you have a MyModel instance, you can use the using keyword to specify the database to save to. The django docs point out some gotchas.

my_model = MyModel(name="Bob")
my_model.save(using='my_non_default_database')
